Mac download (client-side)

Mac download (client-side)

Hi there,
I have a customer who has an Apple Mac (OS X) who I'm trying to support, but recently, we have been unable to start a Zoho Assist session (we managed without problem last year). I suspect the recent problem is due to Apple's clamp-down on Java.

He's installed Java from  http://support.apple.com/kb/DL1572  After entering the meeting ID, he's prompted to download & install a plugin, which he does, but we're then prompted to install the missing plugin again. We seem to be going around in circles.

Is there a Zoho Assist file (DGM?) that he can download to help join the remote session instead, or is he dependent on Java to get things started? He is using the Safari web browser. 

I should add, he tried to get staff at the Apple Store to help, but from what I understand they were disparaging to say the least.

Many thanks in advance for any help you can give.
